Improvement in veneer-cutters



i Ended States WILLIAM STEELE, OF SISTERSVILLE, WEST VIRGINIA.

Lette/rs Patent No. 101,782, dated A11/ril 12, 1870.

The Schedule referred to in these Lettori Patent and making pext of thename.

I, WILLIAMv S'rriLE, of Sistersville, iu the county of Tyler and Stateof West Virginia, have invented.

' certain Improvements in Machinery for Cutting Light Lumber, such asshingles, staves, and backing for ,looking-glass, and picture-frames,from the log, of

which machine(- the following is a specification.

Nature and Object of the Invention.

The first part'of my invention relates to the combining and attachingcutting-knives, ,measuring-rollers, and dividing-cutters, toself-adjusting frames, in such a manner that the weight of said framesalone will hold the knives, cutter, and roller in position to cut thelumber to the desired length and width as it Description oftheAccompanyinglrawngs. Figure 1 is a perspective of my inventionshowing the 'different pa Figure 2 is a longitudinal section of thesame.

Like letters represent like parts in the different figures;

General Description.

The working parts of my'machine are supported by the wooden frame A A.

The knife-frame B, to which are attached the cutting-knife D, thebearing-bar F, and the roller-frame E, is hinged on the upper side ofthe frame A A, and the knife-frame B B is hinged to the under side ofsaidframe A A, so that the knives D and D come in contact with the logon opposite sides, and parallel with each other.

The knife-frames Brand B yB are coupled together by the balance-yokes Gand C, one of said yokes being pivoted on the shaft of the spur-wheel K,and the other on the tighteningserew L.

As the knife-frame B descends, its weight, acting on the yokes G and C,brings the knife-frame B B up with an equal and uniform pressure to thelog.

F is the bearing-bar, which rests upon `the log H, parallel with theedge of the cutting-knife D, and is secured at each end by means ofbolts to the frame B. It is adjustable by means of set screws or thinmetallic backing, so as to regulate the cutting-depth of the knife D andsecure the uniform thickness of the lumber.

E is the roller-flame, which works through slots in the sides of theknife-frame B. p

By means of the spring I, one end of which is bolted yto the knife-frameB lthe other end resting on the 'roller-frame'E, the roller G, providedwith adjustable knives for cutting lumber to any required width, ispressed down to the snrfaceof the log H.

As the log H is revolved by means of the gearing represented by thespur-wheel K and the pinion M, theroller G is also revolved by itsfriction upon the log H, and its knives, by the action of the spring I,

forced into the face of the log H to the required depth.,

The dividing-,cutters J J J are made fast in vertical slots in thebearing-bar F, and, penetrating into the surface of the log H, cut inthe line of motion and separate the timber into the desired length.

In working,the log is centered on the end of the shaftofthe spur-wheelK, and secured in position by the tightening-screw L.

Motion is given by the gearing, composed of pinion M and spur-wheel K,actuated by suitable, pulleys.

As the log revolves the knives are brought in contact with it, cuttingoli' shingles or staves, as may be desired. y

By taking out the roller G and the scoring-knives J J J, the lumber maybe run out in one continuous ,sheet or volute.

To cut shingles, one end of the bearingfbar is raised to the properangle for the butt or thick end of the shingle, the other end of the barto the proper angle for the thin end or top of the shingle, reversingthe adjustment of the ends of the bearing-bar on the under knife-frameB- B, thus preserving a uniform di- `ameter to the log.

In cutting lumber of uniform thickness, one or both knife-frames may beused without affecting the good working of the machine.

Claim.

I claim as my invention the self-adjusting frame B, in combination withthe bearing-bar F, knife D, measuring-roller G, and dividing-cutters J JJ, substantially as described, and for the purpose set forth.

Also, the frame B B with its knife and bearing-bar as connected with theframe B by means of' the balance-yokes C C or their equivalents,substantially as described and for the purpose set forth. y
